Shell scabbard-shaped ; about six times as 

 long as high, the ends rounded, the front and 

 Ijack nearly parallel, white within, and cov- 

 ered without l\y a glossy yellowish or brown- 

 ish-green epidermis, which folds over the sharp 

 edge of the shell. On the surface is a triangle 

 of lines, marking the termination of the longer 

 end at the successive stages of growth ; hinge 

 at one end ; on one valve is a single tooth from 

 which a rib or plate extends to the ligament ; 

 on the other valve are two teeth, and a double 

 plate receiving those of the opposite valve be- 

 tween them ; the terminations of the two ribs 

 rise up in a curved manner and cross each 

 other like teeth, when not broken off, as they 

 usually are. Length of a good specimen, six 

 inches ; height, one inch. A specimen from 

 Halifax, received from Mr. McCulloch, is eight 

 inches long. 



This well-known shell is found on both shores 

 of the Atlantic. It lives on sandy beaches near 



low-water mark, as at Chelsea, Nahant, and 

 Nantasket beaches, about Newburyport, Nan- 

 tucket, &c. Eastport ( Cooper) ; Sable Island 

 and all Nova Scotia ( Willis^ ; Gulf St. Law- 

 rence (^Bell) ; Grand Manan, rare (^StimpsoTi). 

 It is displaced Ijy heavy storms, and thrown up 

 by the tide. It may often be seen at low tide 

 projecting a little above the level of the sand, 

 but, if touched or disturbed, it descends with astonishing rapidity
